PRESERVING AND SHIPPING RECEPTACLE.

Specification of Letters Patent.

Patented Feb. 14, 191-1.

Application filed March 18, 1910. Serial No. 550,249.

BACH and JOSEPH S. AUERBACH, citizens of the United States, residing at the city of New York, New York State, have'invented certain new and useful Improvements in Preserving and Shipping Receptacles, ot

v which the following is a clear, full, and exact description.

This invention relates to improved boxes or receptacles for preservation or shipment of merchandise, particularly such class of goods as spoil or become stale it exposed to the atmosphere, and sudden changes of temperature.

The particular object of theinvention is to provide a box or receptacle so constructed that the contents are maintained in a vacuum or ra'retied atmosphere and are held away from contact with the inside of the exterior walls of receptacle, thus preventing sudden changes of temperature through cons duction of heat.

In carrying out the invention there is provided an impervious outer vessel or receptacle, and an inner vessel of pervious construction or material. Means are provided to hold the inner vessel away from contact with the inner walls of the outer vessel. Spaced supporting strips between the two serve this purpose and efiectually prevent the major part of the inner vessel from contacting with the outer vessels wall. Any known means for creating a vacuum in the two vessels inay be used after the goods have been placed in the inner receptacle. Any suitable valve or valve cover mechanism may be provided to maintain the vacuum until it is desired to get at the contents.

The particular form ot' vacuum retainingl means which is illustrated and described in this specication consists of a cap which may, if desired, be of metal provided with a depending flared out skirt. The outer receptacle may be made of wood, glass or metal and be unyielding. It is preferably provided with a collar or rim around its perimeter, on which y,reposes a continuous band, preferably oit' rubber. I'heilaied skirtot the cover lits and i'ests" ii`siicli band after the vacuum is created and the external air ypressure can then be relied upon to hold the cover tightly in place to maintain the vae 1 substantial improvements over :such modifiuuin previously created.

The scope of the invention will be pointed out in the-eclaim.

In the accompanying drawings: Figure l is a vertical.longitudinal cross section, of a receptacle construct-ed in accordance to' this invention. Fig. 2 is a plan View of such a receptacle with the cover removed. Fig. 3'

is a transverse section on line 3-3, Fig. l. F ig. 4 is a perspective view of a supporting cradle forl the inner box of a moditedform of construction.

In the drawings, l is the Outer vessel, provided with an annular ledge 2 around :its perimeter and with spacing supporting strips 3 on its bottom and like strips 4 on its sides. These'are shown in Fig. l as being integral with the receptacle l itself. I-Iowvever, such strips may take the construction shown in Fig; et and be set into the outer vessel as a separate cradle 5, having cross strips G and vertical strips 7.

A rubber band 8 is placed'around the vessel and rests on the ledge 2. The inner vess`el 9 may be of any material pervious to the air. Cardboard for the candy trade is well adapted for use. I may provide the vessel 9 with perforations l0 for the more ready evacuation of Athat vessel under pump action.

The inner vessel 9 is preferably provided with a cover ll. The outer vessel l is preferably provided with a cover l2, having spacing strips 13 to prevent the cover 1l .from coming in contact therewith, and to strengthen the cover against collapse through the atmospheric pressure upon its surface.

In use the candies or other goods are placed in the inner vessel 9, the cover put in place and the box pushed down or wedged in place upon and between the supporting strips. The cap or cover l2 is then placed in position and the air exhausted by suitable means, and after proper vacuum is established the cover will, as before described, seat itself firmly and tightly on the rubber band and seal the receptacle against entrance of air, because of the external atmospheric pressure.

In carrying out this invention, details of construction may be varied from those sho-wn, and yet the essence ot' the invention be retained; some parts might be employed withouty others, and new features thereof might be combined with elements old in the art in diverse. ways, Yalthough the herein described type is regarded as embodying cations.

As many changes could be made in the tion could be made bev interpreted in an illustrative and not in a limiting sense. lt S-furthermore desired to be understood that the language used in the 'following claim is intended to cover all the generic and. specific features of the in,- vention herein described, and al] statements of the scope of the invention which as a matter of language might be saidto fall therebetween.

" We claim as our invention:

The herein described receptacle 'for preservation or shipment of merchandise Comprising an outer single wall cha mber of inipervious material open at the top and havand many apparently A ing a ledge around the outside of the vessel porting the inner chamber substantially out .of Contact with all the Walle of the outer chamber, a cover for the outer chamber held 1n place merely by atmospheric pressure, having a depending run adapted to lit against the aforesaid Sealing` ringand ineans y:

for holding said cover Substantially out of Contact Withthe ifnner chamber and a `eoin' Imon rar'eiied Space for chambers.
